As a Roblox developer, it is currently too hard to create nice and round moving GUI’s using tweening, so I have two choices: spend my time to make as much tween lines as possible or make a plugin that will automatically smoothen out all those lines. The tri-point tweening should be a feature which allows you to move a GUI on a round trajectory. Just like the current tweening, but adding middle point that streches the curve and an option to make the curve sharper or smoother.
If Roblox is able to address this issue, it would improve my development experience because it will allow me to smoothern out some animations that use GUI’s instead of different decals to reduce lag and such.
On the left one we can see what we can actually do and on the right one we can see a trajectory that a plugin or the tri-point tweening can do.
